This bug is not even marked as fixed yet, so it's way too early to predict LTS backporting plan. We'd first have to fix this in the trunk.

Knowing whether the library is already loaded or not doesn't really help either, because if it's loaded through another classloader, we won't be able to reuse currently loaded copy.

@Koshuke
I've also noticed that I've selected an improper way.
The winp-1.19 should resolve the issue.

> To properly solve this requires a change in the client (and possibly winsw), so that after losing a connection the slave will have winsw relaunch a new service, so that JVM will start fresh.
I suppose it slightly conflicts with "autonomous slaves" approach (slaves may continue operations on temporary disconnects), which usually appears during the infrastructure reliability discussions.

What about checking if the DLL has been already loaded? http://stackoverflow.com/questions/1007861/how-do-i-get-a-list-of-jni-libraries-which-are-loaded/
I suppose that the slave may just log a warning in such case

@Kishore
I'd prefer to recall the proposed Groovy script above, because it may lead to NPEs on uncached resource loads after restarts or plugin updates.
Such solution should be used only on long-run slaves with "warm up" jobs and without class unloading.

@Kohsuke, Do we have a rough idea on which LTS release would have this fix. We are using LTS 1.532 on CentOS for our CI which is expected to be online 24x7x365, and we see this issue that seems to pop up on around 30 of our slaves every week or so.
@Oleg, we would not want the workaround mentioned since all our slaves are not expected to have any overhead whatsoever due to any other running process.

I suppose another simple workaround fix would be to copy winp.dll into another file and load it. It'd work around "already loaded in another classloader" problem.

[jar caching] - winp.x64.dll access conflicts















I've made the change in winp 1.19 to be more intelligent about overwriting the file.

Historically winp uses timestamp based up-to-date check, but because remoting uses timestamp of jar files for LRU checks, this overwrite check was broken. In 1.19 I've switched to checksum-based up-to-date check, which resolves the problem.

But as I was doing that, I noticed a deeper issue here. "Native Library ...\winp.x64.dll already loaded in another classloader " is likely because JNLP slave is retrying after it lost a connection with the master. During the previous connection, the slave has loaded one copy of winp.dll, and after reconnection it's trying to load one more, which is obviously failing.

To properly solve this requires a change in the client (and possibly winsw), so that after losing a connection the slave will have winsw relaunch a new service, so that JVM will start fresh.

This has been a long standing TODO, but it's a good change as it would prevent memory leak and static state clutter over time.

BTW, it is just a workaround. The complete resolution requires some tweaks in the caching procedures.

@Oleg, your latest suggestion worked. 

The job that runs great for me: using the Startup trigger plugin, triggered for a specific label. But, due to some issues in the Startup trigger plugin, with some tweaking: 
install manually version 2.4 
configure the job "This build is parameterized", with a label parameter (the same label as before) and with "Run on all nodes matching the label" checked.

@Horia Constantin
It was a my mistake.
System Groovy script always executes on the master instead of the target slave. 

You can use the Scriptler plugin:
1) Create a Scriptler script

	Write down the groovy call into the script window
	Allow execution by users having "Run Script Permission"
	Check that "Run always on master" is disabled
2) Call this script as a build step inside your job

@Oleg
I'm following your recommendation:
1) Added a freestyle job triggered via the Startup trigger plugin.
2) In the build section, Execute system Groovy script -> Groovy command
3) Just a single line in that field: hudson.remoting.Engine.current().setJarCache(null)

Running the job throws me a "FATAL: Cannot invoke method setJarCache() on null object".
Doing a print of hudson.remoting.Engine.current() in the same build job shows it as null.

If I do this through "There should be a "Script Console" action on the slave's main page" everything runs fine (and I see that hudson.remoting.Engine.current() is not null).

Would you have any idea why this is?

The JAR caching will be disabled, so your slave will have do download all classed from the master node. So the first run of jobs/etc may take more time, but all other runs won't be affected. Actually, it affects distributed systems only.

Disclaimer: This approach works on my installation (1.509.4), but it actually corrupts the normal flow and may lead to serious classloading issues.

You will need a Groovy plugin...

A simple manual approach:
1) Go ${JENKINS_URL}/computer/${NODE_NAME}/script
2) Call "http://arcjenkinsdev/computer/ru20-hw-farm23/script"

After that, the Jar caching will be disabled till the node's reconnection. Please note that it may affect the performance of node.

In order to setup an automatic cache disabling, just use Startup Trigger together with a System Groovy Script build step.

@Oleg 

Thanks for your quick response, could you please mention the  groovy script that you have told above, this is very predominant in our environment and our ci is going for a toss!

@Oleg,
Thanks for quick response.

Can you please be more elaborate on either of options and I am running slave as windows service, which limits me with CLI parameters.

@Murali
Currently there is no solutions or ETAs.

As a workaround, you can disable Jar caching by calling a "hudson.remoting.Engine.current().setJarCache(null)" to disable the cache (e.g. call a System Groovy script on the node).

// Probably, it is possible to pass null via "-jar-cache" CLI parameter.

This issue is killing the whole continuous integration process. Do we have any workaround or any time line to get this fixed?

@Kishore

If I understand toy correctly, you see the following issue:

Unable to render embedded object: File (..can this be fixed please) not found.

If yes, I suppose that this is an another issue. Please create ticket for it
